Expanding the Online Capacity of a Virtual Drive

The Online Capacity Expansion (OCE) function lets you expand the capacity of a virtual disk by adding new physical disks or using unused space on existing disks, without requiring a reboot. Perform the following steps to expand the capacity of a virtual drive.
Attention: Make sure to back up the data on the virtual drive before you proceed with the OCE.
Note: This feature is available only for SAS41xx controllers. For previous generations, the online capacity of a virtual drive cannot be expanded when the existing array size is used. See RAID Level Migration for information on expanding the capacity by doing a RAID level migration.
